Led device for three-dimensional illumination

Abstract

The present invention provides an LED device for three-dimensional illumination, which comprising: a rack 12 and LED chips 2 packaged onto the rack via resin 3; the rack 12 consists of a packaging table 10, and said LED chips 2 are installed on top and all sides of the packaging table 10, such that LED device could emit light on the top and all sides of the packaging table 10. The LED device with wider range of illumination could be widely applied to various lightings.

1 . An LED device for three-dimensional illumination, comprising: a rack ( 1 ) and LED chips ( 2 ) packaged on the rack ( 1 ) via resin ( 3 ); it is characterized by that:
 said rack ( 1 ) is provided with a packaging table ( 10 ), and LED chips ( 2 ) are distributed around and on top of the packaging table ( 10 ).   
     
     
         2 . The device defined in  claim 1 , wherein said rack ( 1 ) consists of: a main body ( 11 ) and a probe ( 12 ) fixed with the main body ( 11 ) and insulated to each other; said main body ( 11 ) consists of a packaging table ( 10 ) and a threaded section ( 111 ), and through-hole is formed within the main body ( 11 ); electrode tips ( 100 ) protruding towards the probe ( 12 ) are set at top of the packaging table ( 10 ); said probe ( 12 ) consists of: a probe body ( 121 ) and terminal formed at one end ( 122 ) of the probe body ( 121 ); the probe body ( 121 ) is inserted from the opening at top of the packaging table ( 10 ), and protruded from the opening of the threaded section ( 111 ); through-holes ( 123 ) for penetration by said electrode tips ( 100 ) are opened on the terminal. 
     
     
         3 . The device defined in  claim 2 , wherein said packaging table ( 10 ) consists of: a flange ( 101 ), and a column ( 102 ) located at the center of the flange ( 101 ); the cross section of the column ( 102 ) is an equilateral polygon, and an LED chip ( 2 ) is distributed at each side of the column ( 102 ). 
     
     
         4 . The device defined in  claim 3 , wherein said probe ( 12 ) terminal ( 122 ) is located at top of the column ( 102 ), and an insulation pad ( 4 ) is set between the terminal ( 122 ) and the top of the column ( 102 ); insulant is filled into the through-hole of the main body ( 11 ) of the rack ( 1 ) into which the probe body ( 121 ) is inserted, allowing for insulation of the main body ( 11 ) and probe ( 12 ) by the insulant and insulation pad ( 4 ). 
     
     
         5 . The device defined in  claim 3 , wherein the flange ( 101 ) of said packaging table ( 10 ) is of a conical slope; a circular groove ( 103 ) is formed on the flange ( 101 ), a transparent cover ( 5 ) is embedded into the circular groove ( 103 ), and the resin ( 3 ) is poured into the cover ( 5 ). 
     
     
         6 . The device defined in  claim 4 , wherein the flange ( 101 ) of said packaging table ( 10 ) is of a conical slope; a circular groove ( 103 ) is formed on the flange ( 101 ), a transparent cover ( 5 ) is embedded into the circular groove ( 103 ), and the resin ( 3 ) is poured into the cover ( 5 ). 
     
     
         7 . The device defined in  claim 5 , wherein an electrode lead ( 21 ) of LED chip ( 2 ) around the column ( 102 ) of the packaging table ( 10 ) is fixed onto the electrode tip ( 100 ), and the other electrode lead ( 22 ) fixed on the terminal ( 122 ) of the probe ( 12 ). 
     
     
         8 . The device defined in  claim 6 , wherein said LED rack ( 1 ) is gold-plated, and the electrode lead ( 21 ), ( 22 ) is made of gold wire.
